- o'4 UNITED STATES E 3 NUCLEAR REGULATORY COMMISSION
_% I WASHINGTON, D.C. 30006 0001 g June 8,1999 LICENSEE: Union Electric Company FACILITY: Callaway Plant, Unit 1
SUBJECT:
MEETING WITH UNION ELECTRIC COMPANY REGARDING THE PROPOSED AMENDMENT TO ALLOW THE INSTALLATION OF {
s ELECTROSLEEVES IN THE STEAM GENERATORS AT THE CALLAWAY PLANT, UNIT 1 (1 AC NO. MA3954) ,
I I
On Thursday,' April 22,1999, a meeting was held between Union Electric Company (UE) and {
the Nuclear Regulatory Commission (NRC) staff to discuss issues regarding Electrosleeved l repaired steam generator tubes during beyond design basis severe accidents. UE submitted an amendment application that requested approval of the Electrosleeve steam generator tube repair method for Callaway Plant, Unit 1. Enclosure 1 is a list of attendees. Enclosures 2 and 4 are the NRC staff's presentation material used during the meeting. Enclosure 3 is the licensee's presentation material used during the meeting.
The staff began the meeting with a presentation of the materialin Enclosure 2. The staff indicated that while Electrosleeves meet current regulatory requirements, there is a concem regarding their performance during beyond-design-basis severe accident conditians. The staff presented preliminary technical results and discussed the information that was used in arriving at these preliminary results. The staff indicated that the preliminary results may indicate the need for a flaw length limitation in the amendment application.
UE then presented the results of the Callaway Plant risk evaluation (see Enclosure 3). UE and the staff discussed actions in the severe accident management guidelines and emergency operating procedures that could decrease the probability of high primary side pressure /
depressurized secondary side severe accident conditions. With regard to the use of fire system water, the staff expressed concems regarding the timing and capability to inject fire water into 4 four steam generator secondary sides, and crediting this action in the risk evaluation.
i
' The moming meeting concluded with the staff presenting one example of conceptual wording for a flaw length limit that could be used, if deemed necessary by the staff. The example is included in Enclosure 4. UE and Frematome Technologies, Inc. (FTI) attendees expressed concems with implementing a flaw length limitation. UE plans to use eddy current examination of the tube to identify a flaw and the need for an Electrosleeve repair. UE then plans to use ultrasonic (UT) examination post-installation to verify the sleeve installation meets j programmatic requirements. However, since UT is more sensitive than eddy current f examination, the post-installation UT results may show scratches that were not indicated by
- eddy current examination before sleeve installation. Due to UT depth sizing qualification still in [

- progress, UE may not be able to distinguish a scratch greater than 1" long from the flaw identified by eddy current testing. The staff indicated that they were open to considering alternatives to the flaw length limit that UE may propose.
- The meeting continued in the afternoon with breakout sessions regarding risk information and .
material behavior of Electrosleeves during high temperature severe accident conditions.
. At the conclusion of the meeting, the NRC staff indicated that based on the information to date, they were still considering the need for a flaw length limitation. UE expressed concerns with the basis for this proposed limitation and implementation issues. UE indicated that implementation issues with the proposed flaw length limit may make the amendment impractical to implement.
These issues will be the topic of further discussion between the staff and UE personnel.
